So I have a 2016 Ram 2500 Megacab with the 6.7 Cummins. I love it. Great truck. It has plenty of tow capacity for us and our current trailer and possible future 5th Wheel upgrade at 16,936lbs.
The problem is that the payload capacity is absolutely horrible at only 1637lbs!! . . .
The empty rear axle weight on the Cummins equipped '16 Ram 3500 SRW megacab and '16 Ram 2500 megacab is nearly identical at ~3100 lbs. RAWR on the 2500 is 6500 lbs. (with 18" wheels/tires) and 7000 lbs. on the 3500.
Bottom line: you have approx. 3400 lbs. of rear axle capacity remaining on your 2500 (and 3900 lbs. of rear axle capacity remaining on a 3500 SRW).
Some folks will tell you don't have this rear axle capacity based on the lower payload and 10k GVWR, but the fact is, based on Ram's own specs, you clearly have 3400 lbs. of rear axle capacity on your '16 Ram 2500 Cummins megacab.
Since the Ram 2500 and 3500 SRW use 99% of the same components, it's easy to deduct the lower payload and 10k GVWR on the 2500 is solely based on the need to pigeon-hole a 2500 (in reality a 3500 SRW with slightly derated rear axle) into a class 2b (3/4-ton) rating for marketing purposes only. Nothing more, nothing less.
A lot of folks will say you need to upgrade to a 1-ton 3500 SRW. Not sure it's worth your time and money just to gain 500 lbs. of additional rear axle capacity.
